Interest .....

You can show it in your return either on accrual basis or at the time of receipt...if the bank has credited the interest and deducted TDS on it (if interest exceeds 10000), then better show it in current year to claim tax credit).

It seems that you have opted for periodic interest payment (by asking the Bank to credit the interest on this special FD, in your savings bank account at fixed intervals), on your 5-year deposit made in March 2011. Then it is necessary for you to show the interest on this FD in the FY in which you received the credit, in your tax return every year.

If you had opted for the cumulative scheme on your FD, then you have the choice to either show the accrued interest (which figure you can obtain from the Bank in April every year) in your tax return every year OR to show the total interest earned for all the 5 years in the FY in which you redeem the FD. However, you have to follow a consistent practice in this regard every year, also taking into account how you show the interest accrued on your other similar bank deposits placed on cumulative basis.
